Two part Question:

A load of 1500N is to be at Height of 3m above the ground. The available Incline planes are 10 degrees and 40 Degrees to the horizontal. Find out the Work Done by effort on the 10 degrees and 40 Degrees ramps. Assume the coefficient of friction is 0.8. Which Incline planes would a weak person use?
